How to Do Barbell Single Leg Squat

  1. 1
    Setup

    Rack the barbell at shoulder height, then load it with appropriate weight. Stand facing the bar, unrack it, and position it across your upper traps, just like a back squat.

  2. 2
    Setup

    Take a small step back from the rack. Shift your weight onto one foot, keeping a slight bend in the knee, and extend the other leg straight forward or slightly behind for balance without putting weight on it.

  3. 3

    Inhale and slowly lower your body by bending the standing knee, keeping your chest up and back straight. Descend until your thigh is parallel to the floor or as deep as comfortable while maintaining balance.

  4. 4

    Exhale and drive powerfully through the heel of your standing foot to return to the starting position. Maintain control throughout the upward movement, avoiding any rocking or swaying.

  5. 5

    Complete all desired repetitions on one leg before carefully re-racking the barbell. Once rested, switch to the other leg to perform the same number of repetitions.

Tips

  • Brace your core throughout the entire movement to maintain balance and spinal stability, preventing unwanted rotation or lateral swaying.
  • Control the eccentric (lowering) phase, slowly descending over 2-3 seconds to maximize muscle engagement and improve stability, rather than dropping too quickly.
  • Start with a light barbell or even just the bar to master the balance and form before gradually increasing the load, prioritizing technique over weight.
  • Fix your gaze on a non-moving point straight ahead to help maintain balance and keep your head and cervical spine in a neutral alignment.

Common Mistakes

  • ×Losing balance and falling forward or backward can be fixed by significantly reducing the weight or starting with bodyweight, and actively engaging your core while focusing on a stable point.
  • ×Rounding the back or leaning excessively forward can be corrected by keeping your chest proud and shoulders pulled back, ensuring your torso remains relatively upright throughout the squat.
  • ×Allowing the standing knee to cave inward can be prevented by actively pushing your knee slightly outward, aligning it over your second or third toe to protect the joint and engage the glutes.
